In this article, we will provide an overview of the API 610 13th edition, its key changes, and what it means for pump manufacturers, users, and the industry as a whole.
API 610 is the international standard governing centrifugal pumps for heavy-duty, high-temperature, and high-pressure applications. These pumps operate in hazardous environments where equipment failure can cause catastrophic safety risks and financial losses. Why the Standard Matters Api 610 13th Edition
The 13th edition of API 610 introduces several key changes, including:
Engineers must meticulously evaluate process conditions before specifying a pump model under the 13th Edition guidelines:
, Centrifugal Pumps for Petroleum, Petrochemical, and Natural Gas Industries , is the globally recognized benchmark for heavy-duty, overhung, between-bearings, and vertically suspended centrifugal pumps. The 13th Edition , published in January 2024, supersedes the 12th edition (2021). It is technically identical to ISO 13709:2024 , aligning American and international standards to streamline global procurement and engineering practices. Submerged or wet-pit designs used when net positive
Define the Best Efficiency Point (BEP), rated flow, and total dynamic head (TDH).
API Standard 610, fully titled “Centrifugal Pumps for Petroleum, Petrochemical, and Natural Gas Industries,” is published by the American Petroleum Institute (API). It specifies minimum requirements for centrifugal pumps used in refinery, oil and gas, petrochemical, and other severe industrial processes. The standard covers overhung pumps (OH types), between‑bearings pumps (BB types), and vertically suspended pumps (VS types), and also applies to pumps operated in reverse as hydraulic power recovery turbines (HPRTs).
Stringent shop tests are mandatory. Manufacturers must map out the pump's performance curve, verifying that total dynamic head (TDH), capacity, power consumption, and vibration limits ( It is technically identical to ISO 13709:2024 ,
Vertical in-line pumps used where floor space is limited. Between-Bearings Pumps (BB Series)
Wet-pit or deep-well pumps. These units handle cryogenic fluids, liquefied natural gas (LNG), and deep sump drainage. 5. Testing and Compliance Requirements
One of the defining features of API 610 is its rigorous testing regime. The 13th Edition continues to require a suite of tests to verify that the pump meets its performance promises:
